Novel styryl dyes containing dithia-15(18)-crown-6(5)-ether moieties were synthesized. Their selective complex formation with Hg2+ and Ag+ ions was studied by (0)1H NMR and electronic spectroscopy; the stability constants of the Ag+ complexes and the relative stability constants (in relation to benzodithia-18-crown-6) of the Hg2+ complexes were determined. The chemical shifts of the beta,beta'-protons in the CH2S group change upon the complex formation in parallel with the logK(1) values of the complexes.

We studied the assembly of dithiacrown ether styryl dye (CSD) molecules in crystals, solutions, and films in the presence of metal cations. X-Ray diffraction data allowed us to conclude that the anion affects the supramolecular architecture of CSDs in the crystal, specifically, the type of stacking of the dye molecules. In solution, in the presence of Pb2+, CSD molecules with the betaine structure
